Abstract: In a magnetic recording system tape is transported bi-directionally across the interleaved head. The interleaved head includes two modules, each module having a plurality of alternate read and write transducer gaps spaced apart along a single gap line transverse to the movement of the magnetic tape. The two modules are placed together so that the write gaps of one module are aligned with the read gaps of the other module. Each module is formed on a nickel-zinc ferrite substrate by deposition of magneto-resistive material to form read transducer elements 69 and deposition of conductor material to form read conductors 74, 76 and 78 and write coils 80. A nickel zinc ferrite closure piece is secured to the substrate to complete the module. In order to provide leveling across the write and read transducers of the module, write back gap islands 90, 92 are provided in the back gap regions 68 of the write coils made of the same material with the same thickness as the magneto resistive element and the conductors interconnecting the magneto resistive element to the read/write network of the tape drive.
